damage the t ires, and t he chains will quickly be
destroyed.
A WARNING
Using incorrect snow chains or installing snow
chains incorrect ly can result in loss of vehicle
co ntrol, which increases the risk of an acc i­
dent .
Snow chains can damage the r ims/wheel cov­
ers* if the chains come into d irect contact
w ith them. Remove the wheel covers* first.
Use coated snow chains .
@ Tips
When using snow chains, it may be useful to

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra­
t io ti res. These t ires have been tho rough ly tested
a n d been se lected specifically fo r yo ur model for
t he ir superb performance, road feel and handling
under a variety o f driving conditions. Ask your au­
thor ized Audi dealer for more details .
The low aspect ratio of these t ires is indicated by
a numera l of
55 or l ess in the tire 's size designa ­
tion. The numera l represents the rat io o f the
tire's sidewall height in relat ion to its tread width
expressed in pe rcentage. Conventional t ires have
a height/w idth rat io of 60 or more.
The performan ce of low- aspect- ratio tire s is par­
ticularl y sensiti ve to imp roper inflat ion pres­
sure . It is therefore import ant that low a spect
ratio tires are infl ated to the specified pressure
and that the inflation pre ssure is regularl y
checked and mainta ined . Tire pre ssure s shoul d
be checked at least once a month and alwa ys
befor e a long t rip
¢ page 217.
What you can do to avoid tire and rim
damage
Low aspect rat io tires can be damaged more easi­
ly by impact with potho les, curbs, gull ies or
Wh eel s
ridges on the road, particular ly if the tire is un ­
deri nflated.
In orde r to min imi ze the occurrence of imp act
damage to the tires of yo ur vehicle, we recom­
mend that you observe the following preca u­
tions:
- Always ma intain recommended inflat io n pres­
sures. Check yo ur ti re pressure every 2,000
miles (3,000 km) and add air if necessary .
- Dr ive ca refully on roads w ith po tholes, deep
gullies or ridges . The impac t from dr iving
through or over such obstacles can damage
your tires. Impact with a curb may a lso cause
damage to your tires.
- After any impact, immediate ly inspect your
tires or have them inspected by the nearest au ­
thorized Audi dealer. Replace a damaged tire as
soon as possible.
- Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear. Damage is not a lways
easy to see . Damage can lead to loss of air and
underinflation, wh ic h could eventually cause
tire fa ilure. If you believe that a tire may have
been damaged, replace the tire as soon as pos­
sib le.
- These tires may wear more quickly than others .
- Please also remember that, while these tires
delive r responsive ha ndling, they may ride less
comfortably a nd make more noise than other
choi ces.
Reduced perfo rmance in winter /cold se ason
conditions
All tires are des igned for certai n purposes. The
low aspect ratio, ultra high performance tires
o rigi na lly installed o n your veh icle are intended
f or maximum dry and wet road per formance and
handling . They are not suitable for co ld, snowy or
icy weather conditions . If you drive under those
c ircumstances, you should equip your vehicle
with all-season or winter tires, which offer better
tract ion under those conditions. We suggest you
use the recommended snow or all-season tires
spec ified for your veh icle, or their equiva lent .
Refer to¢
page 222 for more detailed informa­
t ion regarding winter tires.

Uniform tire quality grading
- Tread wear
- Traction AA A B C
- Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and maximum section width
c::> page 207, fig. 178.
For example: Tread wear 200, Traction AA, Tem­
perature
A.
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades .
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov ­
ernment test course.
For example, a tire graded 150 would wear one
and one half (11/2) times as well on the govern­
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however, and may depart significantly from the norm due to
variations in driving habits, service practices and
differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, Band
C. Those grades represent the tire's
ability to stop on wet pavement as measured un­
der controlled conditions on specified govern­
ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance
¢ &. .
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate­
rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire failure
c::> .&. .
224
The grade C corresponds to a level of perform­
ance which all passenger car tires must meet un­
der the Federal Motor Vehicle Safety Standard
No . 109 . Grades Band A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.
A WARNING -
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor­
nering, hydroplaning or peak traction charac­
teristics.
A WARNING , ~ -
The temperature grade for this tire is estab­
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
Temperature grades apply to tires that are
properly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
(l) General notes
App lies to : vehicles wit h tire pressure mo nitori ng syste m
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
bel, you should determine the proper tire infla­
tion pressure for those tires) .
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant- ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and ""

a:,

LL 00
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to t ire failure. Under-inflation
a lso reduces fuel efficiency and tire tread life,
and may affect the vehicle 's handling and stop ­
p ing ability .
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsib ility to ma intain correct tire pressure,
even if under-inflation has not reached the level
to tr igger illum inat ion of the TPMS low tire p res­
sure telltale.
Your veh icle has also bee n eq uipped w ith a TPMS
malfunct ion indicator to indicate when the sys­
tem is not operat ing properly . The TPMS ma l­
function ind icator is combined w ith the low tire
p ressure tellta le. Whe n the system detects a
malfunct ion, the te lltale will flash fo r approx i­
mately one mi nute and then remain continuo usly
illuminated. This sequence will continue upon
subseq uent veh icle start-ups as long as the ma l­
function ex ists .
When t he malfunction indicator is ill uminated,
the system may not be ab le to detect or signal
l ow tire press ure as intended. TPMS ma lf u nctions
may occur for a var iety of reasons, including the
installation of replacement or alternate t ires or
wheels on the vehicle that prevent the TPMS
from functioning properly . Always c heck the
TPMS malfunction telltale afte r rep lacing one o r

Emerg enc y assis ta nc e
Using th e spa re tire (co mpact sp are tire)
The compact spare tire is only intended for emer­
genc ies until you can reach a repair shop. Repla ce
it as qu ickly as possible with a standard wheel
and tir e.
There are some restrictions on the use of the
compact spare tire . The compact spare tire has
been designed specifically for yo ur type of vehi­
cle. It must not be swapped with a compact
spare tire from another type of vehicle.
Snow chain s
For technica l reasons, the use of snow chains on
the compact spare tire is
not p ermitt ed .
If you do have to dr ive with snow cha ins and a
front tire fails , mo unt the spare wheel with t ire
instead of a rear tire. Install the snow chains on
the rear tire and use it to rep lace the defective
front tire .
A WARNING
-Never use the spare tire if it is damaged or if
it is worn down to the tread wear indicators.
- If the spare tire is more than 6 years o ld,
use it only in an emergency and with ex­
treme caution and carefu l dr iving .
- The spare tire is intended on ly for tempora­
ry and short-term use. It shou ld be replaced
as soon as possible with the normal wheel
and t ire .
- After mounting the compact spare t ire, the
t ire pressure must be checked as soon as
poss ible. The tire pressure of the compact
spare tire m ust be 4.2 bar; otherwise, you
risk having an accident .
- Do not drive faster than SO mph (80 km/h) .
You risk hav ing an accident.
- Avoid full-throttle accelerat ion, heavy brak­
ing, and fast cornering. You risk having an
acc ident.
- Never dr ive using more than one spare
wheel and tire . You risk having an acc ident .
- Normal summer or winter tires must not be mounted on the compact spare wheel rim .
- For technical reasons, the use of tire chains
on the spare tire is not perm itted . If it is
228
necessary to drive with tire chains, the spare
wheel must be mounted on the front axle in
the event of a flat in a rear tire. The newly
ava ilable front wheel must then be installed
in place of the rear wheel w ith the flat tire.
Installing the tire chain before mounting
the wheel and tire is recommended.
- Loose items in the passenger compartment can cause serious personal injury during
ha rd braking or in an accident. Never store
the spare tire or jack and tools in the pas­
senger compartment.
Replacing wheels
· Before changing a wheel
Observe the following precautions for your own
and your passenger's safety when changing a wheel.
.,. After you experience a tire failure, pull the car
well away from moving traffic and try to reach
lev el ground before you stop¢ A_.
.,. All passengers should le av e the car and move
to a safe location (for instance, behind the
guardrail) ¢
&_.
.,. Engage the parkin g brake to prevent your vehi­
cle from rolling unintentionally ¢
A_.
.,. Move the se lector lever to the P p osition.
.,. If you are towing a trai ler: unhitch the trailer
from your vehicle.
.,. Take the
jack ¢ page 22 7 and the sp ar e ti re
¢ page 227 out of the luggage compartment.
A WARNING
You or your passengers could be injured while
changing a wheel if you do not follow these
safety precaut ions:
- If you have a flat tire, move a safe distance
off the road . Turn off the eng ine, turn the
emergency flashers on and use other warn­ ing dev ices to alert other motorists.
- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traff ic.
- To help prevent the veh icle from moving
suddenly a nd possibly slipping off the jac k,

always fully set the parking brake and block
the wheel diagonally opposite the wheel be­ ing changed with the folding chocks or oth­
er objects. When one front wheel is lifted
off the ground, placing the Automatic
Transmission in "P" (Park) will
not prevent
the vehicle from moving.
- Before you change a wheel, be sure the
ground is level and firm. If necessary, use a
sturdy board under the jack.
- Always store the vehicle tool kit, the jack*
and the replaced tire in the luggage com­
partment
